Actually it seems to be a site wide problem with IE. If I disable compatibility mode it goes away for the most part but in the link above it persists with or without compatibility mode. *shakes fist at Internet Explorer* Please help because around 30% of my visitors still live in 2001 and are using IE.

It was doing it in IE7 and 9. I narrowed it down to an image in my post being wider than what would fit. This was forcing the right sidebar to be moved to underneath the post. I think I have it working correctly now.
